From c75793d8ab743acdd07120cf11c0242daea8f780 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 6 Mar 2014 10:31:15 +0100 Subject: gpio: max732x: Fix I2C dummy device resource leak on probe failure In max732x_probe() driver allocates dummy I2C device (if number of ports is greater than 8) however it is not unregistered if probe fails later. Fix the leak by unregistering dummy I2C device if it was allocated.
